History

The Sam Rayburn Tollway project was divided into five segments, all of which have been completed. * Segment 1, from Denton Tap Road to Old Denton Road, opened to traffic in July 2006. * Segment 2, which runs from Old Denton Road to Hillcrest Road, officially opened to traffic on September 1, 2008, when NTTA took full responsibility for Segments 1 and 2 as well as the operation, maintenance and construction of the remaining segments of the SRT. * NTTA contractors began work on Segment 3 of the SRT in March 2008. On September 1, 2009, the NTTA opened the main lanes from Hillcrest Road to just east of Custer Road. On September 29, 2009, the NTTA opened the main lanes from just east of Custer Road to west of Hardin Boulevard. * Segment 4 encompasses the Sam Rayburn Tollway/U.S. 75 interchange, from west of Hardin Boulevard to just east of U.S. 75. Construction on this portion of the corridor began in December 2008. Four major direct-connecting ramps were open to traffic in December 2010. The last two ramps were opened in March 2011. * The Sam Rayburn Tollway/Dallas North Tollway interchange is referred to as Segment 5. The NTTA began construction on Segment 5 in February 2010. It was completed in 2012.
